The total ratio is 5

The number of comedy movies watched is 12

The number of other movies watched is 18

Ratio is a comparison of two or more numbers that indicates their sizes in relation to each other. Therefore,

He has watched 2 comedy movies for every 3 other movies. The total movies he has watched is 30. Therefore,

Ratio of comedy to total movies is as follows:

number of comedy movies watched = 2 / 5 × 30 = 60 / 5 = 12

number of other movies watched = 3 / 5 × 30 = 90 / 5 = 18

Therefore,

total ratio = 5

number of comedy movies watched = 12

number of other movies watched = 18

Answer:

(9, - 9 )

Step-by-step explanation:

P (2, 3 ) → P' (5, - 4 )

2 → 5 in the x- direction is + 3

3 → - 4 in the y- direction is - 7

translation rule is then (x, y ) → (x + 3, y - 7 ) , so

(6, - 2 ) → (6 + 3, - 2 - 7 ) → (9, - 9 )

Answer:

corresponding angles . the answer

Answer:

corresponding angles

Step-by-step explanation:

its called the corresponding angles and are equal value

Answer:

11.8° and 78.2°

Step-by-step explanation:

let the angles be x and x + 66.4

complementary angles sum to 90° , then

x + x + 66.4 = 90

2x + 66.4 = 90 ( subtract 66.4 from both sides )

2x = 23.6 ( divide both sides by 2 )

x = 11.8 and

x + 66.4 = 11.8 + 66.4 = 78.2

The 2 angles are 11.8° and 78.2°

The equation that represents the amount of soil, s in cubic centimeters the ferret can dig from the burrow in m minute is as follows:

s = 93m

One of the ferrets digs 465 cubic centimeters of soil from a burrow in 5 minutes.

The digging rate can be calculated as follows;

A rate is a ratio between two related quantities in different units. Therefore,

rate = 465 / 5 = 93 cubic centimetres per minutes.

Answer:

5x^2 - 8x - 32

Step-by-step explanation:

Area of rectangle = base x height

Area of larger rectangle = (3x - 8)(2x + 4)

                                        = 6x^2 - 4x - 32

Area of smaller rectangle = (x + 4)x

                                           = x^2 + 4x

Area of shaded region = area of larger rectangle - area of smaller rectangle

                                      = (6x^2 - 4x - 32) - (x^2 + 4x)

                                      = 5x^2 - 8x - 32

Answer:

Step-by-step explanation:

When we say "y varies inversely as x", we mean that y is proportional to the inverse of x: y = k·(1/x). This relation is usually written ...

  y = k/x

It can be solved for the other values:

  xy = k . . . . multiply by x

  x = k/y . . . divide by y

If you are given the equation, the value of k can be read directly from it: it is the constant in the numerator.

__

  k = xy = 5·6 = 30; the equation is y = 30/x

  y = k/x = 36/4 = 9; the equation is y = 36/x

 k = 50 (read from the equation); x = k/y = 50/20 = 5/2

  k = 24 (read from the equation); y = k/x = 24/12 = 2

Answer:

  A) x = 2; y = 2; (m, n) = (1/2, 0); (p, q) = (-3/2, 12)

  B) K; A and E

  C) 11

Step-by-step explanation:

With the exception of the vertical line, the equations of the lines can be written in terms of their slope and y-intercept. The slope is the ratio of "rise" to "run". The "rise" is the vertical change between points, and the "run" is the horizontal change between the same points. Changes to the right or up are taken as positive. The change amounts can be read from the graph by counting grid squares, or by subtracting coordinate values.

The regions described by an inequality will be to the right of a boundary line for x > (boundary), and above the boundary line for y > (boundary). When these inequalities are reversed, the region will be left or below the boundary, respectively.

__

The slope-intercept equation for a line is ...

  y = mx +b . . . . where m is the slope, and b is the y-intercept

(i) x = 2 . . . . . . points on the vertical line have an x-value of 2

(ii) y = 2 . . . . . 0 slope, y-intercept of 2

(iii) m = 1/2, n = 0 . . . . rise = 1 for run = 2; y-intercept = 0

(iv) p = -3/2, q = 12 . . . . rise = -3 for run = 2; y-intercept = 12

__

(i) Region K is to the right of the vertical line, and above the two slanted lines

(ii) Regions A and E are below y=2 and the two slanted lines

__

The maximum value of x+y will be found at the point on the line x+y=c, where c is the largest possible value. That is, it will lie on the line ...

  y = -x +c . . . . a line with a slope of -1

such that the line is as far as possible from the origin.

For region G, the point that maximizes "c" in the above equation is point (2, 9), so ...

 c = x +y = 2 +9 = 11

The maximum value of (x+y) in region G is 11.

The absolute value parent function, f(x) = | x |, is defined as:

[tex]f(x)=\begin{cases}x \; &\text{if}\;x > 0\\0 \; &\text{if} \; x=0\\-x\; &\text{if}\;x < 0\end{cases}[/tex]

Therefore:

Its graph is V-shaped and has the following properties:

Given absolute value expression:

[tex]|3x+12|[/tex]

Simplify the given expression:

[tex]\implies |3x+12|=|3(x+4)|=3|x+4|[/tex]

Set the simplified absolute value expression to zero and solve for x:

[tex]\begin{aligned}\implies 3|x+4|&=0\\|x+4|&=0\\x+4&=0\\x&=-4\end{aligned}[/tex]

Therefore, the vertex of the graph of the given absolute expression is (-4, 0).

Therefore, the slope of the expression will be positive for values of x greater than -4, and negative for values of x less than -4.  Set the expression inside the absolute value sign to positive and negative to find the two expressions with positive and negative slopes:

[tex]|3x+12|=\begin{cases}3x+12 \; &\text{if}\;x > -4\\0 \; &\text{if} \; x=-4\\-3x-12\; &\text{if}\;x < -4\end{cases}[/tex]

Given absolute value expression:

[tex]|(x-19)+11|[/tex]

Simplify the given expression:

[tex]|(x-19)+11|=|x-19+11|=|x-8|[/tex]

Set the simplified absolute value expression to zero and solve for x:

[tex]\begin{aligned}\implies |x-8|&=0\\x-8&=0\\x&=8\end{aligned}[/tex]

Therefore, the vertex of the graph of the given absolute expression is (-8, 0).

Therefore, the slope of the expression will be positive for values of x greater than 8, and negative for values of x less than 8. Set the expression inside the absolute value sign to positive and negative to find the two expressions with positive and negative slopes:

[tex]|(x-19)+11|=\begin{cases}x-8\; &\text{if}\;x > 8\\0 \; &\text{if} \; x=8\\8-x \; &\text{if}\;x < 8\end{cases}[/tex]

Given absolute value expression:

[tex]|14-(x-6)|[/tex]

Simplify the given expression:

[tex]|14-(x-6)|=|14-x+6|=|20-x|[/tex]

Set the simplified absolute value expression to zero and solve for x:

[tex]\begin{aligned}\implies |20-x|&=0\\20-x&=0\\x&=20\end{aligned}[/tex]

Therefore, the vertex of the graph of the given absolute expression is (20, 0).

Therefore, the slope of expression will be positive for values of x greater than 20, and negative for values of x less than 20. Set the expression inside the absolute value sign to negative and positive to find the two expressions with positive and negative slopes:

[tex]|14-(x-6)|=\begin{cases}x-20 \; &\text{if}\;x > 20\\0 \; &\text{if} \; x=20\\20-x \; &\text{if}\;x < 20\end{cases}[/tex]

Given absolute value expression:

[tex]|14-(6-x)|[/tex]

Simplify the given expression:

Set the simplified absolute value expression to zero and solve for x:

[tex]\begin{aligned}\implies |x+8|&=0\\x+8&=0\\x&=-8\end{aligned}[/tex]

Therefore, the vertex of the graph of the given absolute expression is (-8, 0).

Therefore, the slope of expression will be positive for values of x greater than -8, and negative for values of x less than -8.  Set the expression inside the absolute value sign to positive and negative to find the two expressions with positive and negative slopes:

[tex]|14-(6-x)|=\begin{cases}x+8 \; &\text{if}\;x > -8\\0 \; &\text{if} \; x=-8\\-x-8 \; &\text{if}\;x < -8\end{cases}[/tex]

Answer:

Step-by-step explanation:

d(t) = 4t + 382 - 16t²

where d is the distance (in feet) between the rock and ground t seconds after thrown. Ground is 0 feet.  As a note, I'm not clear why the "4t" term is in this equation.  It has the effect of adding an increase in height at the rate of 4 feet/sec.  I'll assume this is to accommodate any increase in height due to the throw, but it is a bit curious.  

a.  How long after the rock is thrown is it 370 feet from the ground?

The 382 in the equation represents the starting height of the rock (382 feet).  To find the time to reach 370 feet:

370 = 4t + 382 - 16t²

Solve using the quadratic equation.  There will be two answers, one negative, which we'll discard until we can go backwards in time.  The positive value is 1, which would mean the rock will be at 370 feet in 1 second after throwing.

b. After how many seconds will the rock reach the ground?

Ground is 0 feet:

0 = 4t + 382 - 16t²

t = 5 seconds

c. What is the height of the rock when it is halfway to the ground?

The initial height is 382 feet, as per the equation, since when t = o (initial), d(t) is 382 feet.  Halfway to the ground would be (382/2) or 191 feet.
